I have a 32 inch sharp tv and it has been working fine, but i just went to watch a dvd and got sound from the dvd but a green, disjointed pattern instead of pictures. i switched dvds and it was the same time and then i actually tried a different dvd player and it was the same thing; static green pattern, sound from the dvd, but no picture.
anythoughts would be welcome.

There is a possibility that you have switched the RCA cables for the right port, the color patterns happen if your plug the component RCA ( Y Pb Pr) on a diff port. their usually color coded so please double check that to.

if not, please let us know what is the model number of the TV and we will find what can be done in the TV.

try channel Line 1 or Line 2 on your TV and or VCR... not channel "3" if you're using "RCA cords". Also, make sure your VCR and TV are "SETUP" to look for composite input's rather than coaxial.
good luck!

Take off back cover. The problem power board is to the right of the
board where the power plug feeds into the TV. There is a large white
fuse right bend the power plug. With a meter it read ok; about 8 inches
deeper into the TV on that board was the resister next to two fuses. My
4 amp 125 volt fuse did not read on my meter. After replacing, it
worked fine.
